Optical rotation devation ± 13

Application

DuPhos and BPE Ligands: Highly Efficient Privileged Ligands

(R,R)-i-Pr-DUPHOS is a chiral phospholane class of ligand that can be used in:

• The catalytic asymmetric hydrogenation reactions.
• Rhodium catalyzed enantioselective synthesis of 1,2 diols via asymmetric intramolecular hydrosilylation of α- and β-hydroxyketones.
• In the enantioselective synthesis of diarylmethanols by arylation of aromatic aldehydes with arylboronic acids in the presence of a rhodium catalyst.
